Abstract: The invention is a positive displacement heat engine; where the engine cycle comprises the steps of Ericsson (isothermal) compression, recuperative heat addition, Brayton (adiabatic) expansion, and recuperative heat removal; whose principle is heat addition to the cycle by an afterburner in which fuel is burned with the low pressure air working fluid exhausted by the expander.
